That's a lot of photos of you trying to capture the look of someone having the absolute time of your life so you can make your Facebook friends jealous.

This got us thinking. Twenty-five thousand selfies are a lot, but that number is no doubt subject to change because we all live a different amount of time before the Grim Reaper comes calling. So, how many selfies do you take in the course of a day? How long can you go without taking one? And, most importantly, are there any places you think it's totally inappropriate to snap one? We know it's not smart to take them near a train because there's the distinct possibility that they just may kill you.
